3. Driving or operating on the slope It is dangerous to drivingoperating on the slope. Be care! 1) It suggests not upgrade or
downgrade on the slope which the gradient more than 200
2) When the machine works, it need to tie the safety belt especially on the upgrade or downgrade and the danger area
3) When the digger upgrades, the drive wheel need towards the direction which under the slope. It should let the moving-armlever with the slope parallel, the gear of the bucket have 20-30cm distance from the ground. And lock the platform then upgrade low speed.
4) When the digger downgrade, it locks the platform. The drive wheel need towards the direction which up the slope. Elongate the moving-armlever , and the gear of bucket have 20-30cm distance from the ground, then downgrade low
speed. 5) No allow to swerve on the
slope or pass the slope, it must replace the machine’s place on the next flat place, then upgrade.

6) When the machine operates on the slope, it must start the high first ,then towards the direction of the downgrade. The Bulldozer backs it, and press the ground, the place for remove the soil on the direction of the upgrade.
7) It need drives low speed on the leathe shatter the wet armor plate
8) No allow to swerve when the machine upgrade or downgrade. Otherwise, the machine maybe overturn.
9) When the machine stops on the slope, it must make the bulldozer into the ground, and make the bucket into the ground, too. After it stop placidly, and then stop the engine, and the operator out.
10) No driving or operating on
the slope which the portrait gradient more than 250
11) Don't driving or operating on 10) the slope which the
landscape orientation gradient more than 250
9) As far as possible to keep the machine balanceable, no
Danger It is very dangerous to stop the machine on the slope, please do as follows if have to be: Please put the dozer blade and the bucket on ground immediately if the engine is stop running on the slope, and pull the control handle to middle position before restarting. Even the machine is stop on the slop temporary, please also lower the bucket and dozer blade on the ground, pull the control handle to middle position and put the block to fix the machine at lower end of the tracks.
